OFFSCALE

The OFFSCALE message shows on the ND when an RA or TA is outside the current ND display area. The TFC switch on the EFIS control panel must be set to ON to show the OFFSCALE message. If an RA is outside the ND range, the OFFSCALE message shows in red. If a TA is outside the ND range, the OFFSCALE message shows in amber. If both a TA and RA are outside the ND range, the OFFSCALE message shows in red.
